YUNZII B75 PRO Wireless Mechanical Gaming Keyboard 75% Knob White Cocoa V2 Switch

Compact 75% Layout with Control Knob

The YUNZII B75 PRO is a 75% mechanical gaming keyboard that keeps the function row and arrow keys while saving desk space. It uses a gasket-mount structure with five layers of internal padding to reduce hollow sound and deliver a creamy typing feel. A multifunction knob on the top-right corner adjusts volume, backlight brightness and switches between gaming and office modes with a long press. The board is aimed at gamers and typists who want a compact form factor without losing dedicated navigation keys.

Tri-Mode Connectivity with 4000mAh Battery

The single specification that determines compatibility is the triple connection method: Bluetooth, 2.4 GHz wireless via a USB receiver, and wired USB Type-C. A built-in 4000mAh lithium-ion battery powers the wireless modes for extended sessions, and the keyboard can be used while charging over the Type-C cable. No proprietary dongle or software driver is required for basic operation on Windows or macOS.

Hot-Swap Sockets and South-Facing RGB

Installation is straightforward because the PCB uses hot-swap sockets that accept any 3-pin or 5-pin MX-style switch without soldering. The switches come pre-lubed from the factory, and the double-shot PBT Cherry-profile keycaps are already mounted. South-facing LEDs shine through the legends without interference from the keycap stems. The most common issue is forgetting to toggle the physical mode switch on the underside when moving between Bluetooth, 2.4 GHz and wired connections.
